Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.

An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.

The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Question to determine the respondent’s current age using his or her date of birth.

Purpose:

Current age is a critical component of a respondent’s demographic background. Date of birth (DOB)/current age is essential to medical research because it captures the age at the time of the clinical visit or diagnosis. Age is related to nearly all diseases and conditions and is the strongest potential confounder of other effects on these processes. Current age is often used to stratify respondents for more valid comparison (e.g., obesity of males aged 40-45 in Mississippi).
